feat: Enhance configuration management with new LLM provider support and API integration

- Backend: Introduced new endpoints for LLM configuration retrieval and updates in `config.py`, allowing dynamic management of LLM provider settings.
- Updated schemas to include `AlphaEngineConfig` for better integration with the new provider.
- Frontend: Added state management for AlphaEngine API credentials in the configuration page, ensuring seamless user experience.
- Configuration files updated to reflect changes in LLM provider settings and API keys.

BREAKING CHANGE: The default LLM provider has been changed from `new_api` to `alpha_engine`, requiring updates to existing configurations.
